What You Can Expect
Our scientists work closely with you to understand your study's objectives and design a project to quickly and efficiently achieve your goals, from sample size considerations to the most appropriate technology platforms for discovery and validation.
Technologies We Use
RayBiotech Multiplex Arrays
We can use off-the-shelf or custom multiplex arrays that utilize antibody-based detection quantitatively or semi-quantitatively to detect a wide range of analytes with high sensitivity.
RayPlex® Bead-Based Arrays
RayPlex® Bead-Based Arrays are an advanced technology that uses antibody-conjugated multiplex beads to quantitatively measure a wide range of analytes in a liquid phase at high sensitivity.
- Compatible with a variety of sample types including whole blood, PBMCs and other primary and immortalized cell lines.
- Detects up to 50 targets proteins.
- Up to 12-color or 18-color analysis.
- Custom and pre-validated panels are available.
- Minimal sample volume required per test.
Quantitative Multiplex ELISAs
Quantibody® glass slide arrays are sensitive, quantitative multiplex ELISAs.
- Fully validated assays for cytokines, chemokines, growth factors, soluble receptors, and many more molecule classes.
- Available for biomarker discovery of >1200 human proteins, >640 mouse proteins, and proteins in other species including rat, sheep, chicken, cow, pig, horse, dog, primate, rabbit, cat, and dolphin.
- Quantifies up to 40 proteins using just 50 µL of sample.
Semi-Quantitative Multiplex Screening Arrays
Maximize the number of targets you can assess with RayBiotech L-Series Screening Arrays. This approach relies on direct labeling of sample proteins with biotin, enabling detection through binding with labeled streptavidin, avoiding the need to develop validated antibody pairs.
- pre-made or customized biomarker panels available
- >8000 human >1308 mouse target proteins
- Just 10 µl of sample required
Post-translational Modification Arrays
RayBiotech's suite of PTM profiling tools includes easy-to-use antibody arrays to screen up to 8,000 target proteins for acetylation, palmitoylation (acylation), oxidation, nitrosylation, glycosylation, or phosphorylation signatures.
Protein and Peptide Arrays
Protein arrays are spotted with immobilized proteins or peptides to profile serological (auto)antibodies as well as study protein interactions with other proteins, peptides, DNA, and drugs. Choose from our pre-established disease specific panels or customize a unique panel.
RayBiotech ELISAs
Choose from over 6000 targets across 15 different species and 7 different ELISA platforms for single target biomarker detection and validation
- Sandwich ELISA
- Phosphorylation ELISA
- High-Sensitivity Immuno-PCR
- Competition-based ELISA
- Cell-based ELISA
- Chemiluminescent Immunoassay (CLIA)
- Transcription Factor Activity Assay
Simoa®
Single molecule array (Simoa®) testing is a powerful technique that utilizes the isolation of individual immunocomplexes on paramagnetic beads to generate data that is orders of magnitude more sensitive than standard sandwich-based immunoassay techniques.
- Choose from a library of over 4,000 targets.
- Sensitivity as low as femtogram (fg/mL) concentrations.
